The temperature at 9 AM was 13°F, If the temperature is -2°F at 6 AM and the next three hours the temperature increases 15°F.
Step-by-step explanation:
The given is,
Temperature is -2°F at 6 AM
For the next three hours from 6 AM the temperature increases 15°F
Step:1
We need to find the temperature at 9 AM,
Let, X - Temperature at 6 AM
Y - Temperature at 9 AM
Step:2
Where,
X = -2°F
From the given, Y becomes
( during the next three hours the temperature increases 15°F )
Y = X + 15
Substitute the X value,
= (-2 + 15)
Y = 13°F
Result:
Thus the temperature at 9 AM was 13°F, If the temperature is -2°F at 6 AM and the next three hours the temperature increases 15°F.
(y2-y1)/(x2-x1)
(5-1)/(-1-1)
4/-2 = -2
Answer:
5
Step-by-step explanation:
Answer:
I believe it would be the 3rd answer.
Step-by-step explanation:
That answer is the only one where not only do one of the systems have that point but they both do. That is where they intercept. Plus when you fit in the x and y points in the equations they match up. Hope that helps!
The answer is 4/2. If you want to simplify it it'll be 2/1.
